Just google “citric acid GERD” and you’ll find that citric acid triggers acid reflux. This includes the many products that contain it as an additive.

I can Google all sorts of things and find sources to back up whatever ridiculousness I want to assert. That, of course, doesn't make it true.

Can citric acid consumption cause or exacerbate acid reflux? Sure. If you consume enough of it. You can die from drinking too much water, after all.

What I'm saying is that the amount used in foods, beverages and pharmaceuticals is so small that it will have no impact on the average person. All bets are off however, if someone drinks a case of Mountain Dew every day.
